Hi Guys,

The brightness controll not works on R528/530. There are a nVidia Corporation GT218 [GeForce 310M] (rev a2)

What can I do?

Thanks for help!

You must write the Option "RegistryDwords" "EnableBrightnessControl=1" row in the xorg.conf.

add "acpi_backlight=vendor" argument in grub, and it will work

hello
i have samsung R530 i am absulutly beginner
how i will change those setting the only problem i have is the brightness

sorry for my but english

Hello!

You must install the closed source nVidia driver. (I don't know the english name, because I use my Ubuntu in Hungarian language)
You must restart your computer. Login, and sudo gedit /etc/X11/xorg.conf
Xou mudt insert a row, under the Option "NoLogo"

Option "RegistryDwords" "EnableBrightnessControl=1"

On the R530, you can install these packages:

easy-slow-down-manager
nvidia-bl-dkms
samsung-backlight
samsung-tools
and you must update all files (kernel)

If you finish, you must restart your computer.
If you OK, the brightness will OK.

is working thank you very much but i had problem installing samsung tools and samsung backlight
if any body can have a look

Maybe it's helps for you:

Open a terminal:

sudo add-apt-repository ppa:voria/ppa
sudo apt-get update && sudo apt-get upgrade
sudo apt-get install samsung-tools samsung-backlight

Reboot

i did that is say to me the package is broken

I don't have idea.
